How we score

We score each thing that comes up most in owner feedback on the Karaoke Machine for Kids. Four things come up most in owner feedback: all four draw praise. Its ratings average 4.6 stars (82% five stars, 9% four, 5% three and 4% one or two), so every score starts at 92, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read six owner reviews in full (every one we found gave it four or five stars) and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.6 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Nothing comes off here, so it stays at 4.6. Read our editorial standards

1. Charge Everything First

   Use the two charging cables in the box to charge the machine and the microphones fully before the first session, so the first party does not end with a flat mic.

2. Pair a Phone or Tablet

   Turn the speaker on, open the Bluetooth settings on your phone, tablet or laptop and select the karaoke machine from the list. It should be up and running within minutes, and the connection holds once paired.

3. Switch On Both Microphones

   Turn on both wireless mics and check that each one picks up your voice before handing them over. Both work at the same time, so two singers can share a song.

4. Set the Volume

   Start low and raise the volume with the buttons on the machine until the music and the voices sit comfortably together. It gets louder than its size suggests, so a small room rarely needs it at full volume.

5. Try the Vocal Key and Magic Voices

   Press the vocal key while a Bluetooth song plays to lower the original singer, and press it again to bring the vocals back. Then try the four magic voices for playful effects on the mic.

6. Choose Lights or Headphones

   Let the LED lights pulse with the music for a party feel, or plug headphones into the output on the back so a child can hear their own singing during quieter practice.
